Composition of tocopherols, tocotrienols, carotenoids, fatty acids, as well as hydrophilic and lipophilic antioxidant activities, were determined in seeds of two Salvia species and oils obtained from them. Both seeds contained a large amount of oil (around 20%) rich in polyunsaturated fatty acids. While Salvia officinalis seed oil can be classified as oleic-linoleic oil, the predominant fatty acid in Salvia sclarea was α-linolenic acid (around 54%). Among tocols, the main isomers in both seeds and oils were γ-tocopherol, followed by α-tocopherol. Concerning carotenoids, their concentration was around 0.75 mg/100 g of seeds and 0.16 mg/100 g of oils, with a predominance of lutein. Oil and seeds of S. officinalis exhibited higher antioxidant potential compared to S. sclarea investigated samples which could be attributed to higher content of total vitamin E and carotenoids. This study provides results that enables use of two Salvia species as new alternative sources of vegetable oils.
测定了两种鼠尾草种子及其所产油中的生育酚、生育三烯酚、类胡萝卜素、脂肪酸的组成，以及亲水性和亲脂性抗氧化活性。两种种子都含有大量（约20%）富含多不饱和脂肪酸的油。鼠尾草种子油可归类为油酸 - 亚油酸型油，而南欧丹参种子中的主要脂肪酸是α-亚麻酸（约54%）。在生育酚中，种子和油中的主要异构体都是γ-生育酚，其次是α-生育酚。关于类胡萝卜素，其浓度约为0.75毫克/100克种子和0.16毫克/100克油，以叶黄素为主。与所研究的南欧丹参样品相比，鼠尾草的油和种子表现出更高的抗氧化潜力，这可能归因于总维生素E和类胡萝卜素的含量更高。本研究提供的结果使得两种鼠尾草能够作为植物油的新替代来源。
